Quails belong to the order of pheasants (Phasianidae). This order has the following subfamilies — grouse, guineafowl, turkey and the American quail. In India, a very vulnerable species of quail is the Manipur Bush-quail (Perdicula manipurensis) which is found only in West Bengal, Assam, Nagaland, Manipur and Meghalaya. They are found in very small numbers in Bangladesh chiefly in the Chittagong Hill Tracts and Sylhet district. They live in damp grasslands and swamps. Quails are ground birds, and rarely, if ever, fly. They are well camouflaged and rarely seen in open grounds where coveys might sometimes be spotted feeding. This species of quail is a dark bush-quail with a rich buff belly and vent. It is mostly dark greyish, with a whitish loral patch, a golden belly and a vent with black markings. Very little is known about it and although scientists and bird watchers are trying to study this species, their numbers are declining due to habitat degradation and hunting.
